  • The Fairbanks Morse 6CT4-B is an battery operated, 6 tube BC, Police and SW band receiver. Has 5.5" dial with a 16:1 tuning ratio.  Also has tuning eye, copper chassis, AVC, tone control and 2 stage audio circuit with push-pull output. Has BIAS CELL in grid circuit of 6T7G detector/triode tube. Uses vibrator circuit to create the B+ voltage.

    Band Frequency Ranges are as follows:
    BC Band......................540 - 1730kHz
    Police Band.................1.7 - 5.7MHz
    SW Band....................5.6 - 18.3MHz

    NOTE: 6C is the chassis number and NOT the model number.

    PRODUCTION CHANGE NOTE:  A production change was made on the chassis, changing the 2W, 10 Kohm resistor (Reference designation 15 on schematic) to a 2W, 22Kohm resistor, which is in the screen grid circuit of the 6D8G and 15 tubes (See Riders volume 10, changes section 10-2).
